In Spring Boot - the application database is not creating - java

I am creating a Spring Boot application. While I am running the application database table is not creating.
Here is my application.properties file
spring.datasource.url=jdbc:mysql://localhost/aymuws
spring.datasource.username=root
spring.datasource.password=1101289217
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=create-drop
The User repository class
package com.technostack.aymuws.entities;
#Entity
#Table(name="user")
public class User {
#Id
#Email
#NotEmpty
#Column(unique=true)
private String email;
#Column(name="_name",unique=false,nullable=false,length=100)
#NotEmpty
private String name;
#Column(name="_password",unique=true,nullable=false)
#NotEmpty
#Size(max=12,min=6)
private String password;
#Column(name="_task")
#OneToMany(mappedBy="user",cascade=CascadeType.ALL)
private List<Task> tasks;
#Column(name="_roles")
#ManyToMany(cascade=CascadeType.ALL)
#JoinTable(name="USER_ROLES",joinColumns= {
#JoinColumn(name="USER_EMAIL",referencedColumnName="email")
},inverseJoinColumns= {
#JoinColumn(name="ROLE_NAME",referencedColumnName="name")
})
private List<Roles> roles;
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public List<Task> getTasks() {
return tasks;
}
public void setTasks(List<Task> tasks) {
this.tasks = tasks;
}
public List<Roles> getRoles() {
return roles;
}
public void setRoles(List<Roles> roles) {
this.roles = roles;
}
public User(String email, String name, String password) {
this.email = email;
this.name = name;
this.password = password;
}
public User() {
}
}
The Task repository class
package com.technostack.aymuws.entities;
#Entity
public class Task {
#Id
#GeneratedValue
private Long task_id;
#NotEmpty
private String date;
#NotEmpty
private String starttime;
#NotEmpty
private String stoptime;
#NotEmpty
private String description;
#ManyToOne
#JoinColumn(name="USER_EMAIL",referencedColumnName="email")
private User user;
// Constructors, setters & getters
}
And the Role repository class
package com.technostack.aymuws.entities;
#Entity
public class Roles {
#Id
private String name;
#ManyToMany(mappedBy="roles")
private List<User> users;
// Constructor, getters and setters
}
The Service class is the following.
package com.technostack.aymuws.service;
#Service
public class UserService {
#Autowired
private UserRepository userRepository;
public void createUser(User user) {
BCryptPasswordEncoder encoder = new BCryptPasswordEncoder();
user.setPassword(encoder.encode(user.getPassword()));
Roles user_role = new Roles("USER");
List<Roles> create_role = new ArrayList<>();
create_role.add(user_role);
user.setRoles(create_role);
userRepository.save(user);
}
public void createAdmin(User user) {
BCryptPasswordEncoder encoder = new BCryptPasswordEncoder();
user.setPassword(encoder.encode(user.getPassword()));
Roles user_role = new Roles("ADMIN");
List<Roles> create_role = new ArrayList<>();
create_role.add(user_role);
user.setRoles(create_role);
userRepository.save(user);
}
public User findone(String email) {
return userRepository.findOne(email);
}
}
Here is the console when I run the application.

I am configuring all the database information in properties file. However, after executing the application I am not being able to create the database.

Change to this configuration in application.properties and see if its working

spring.datasource.url = jdbc:mysql://localhost:3306/aymuws?autoReconnect=true&verifyServerCertificate=false&useSSL=false&requireSSL=false

Permission denied in getting spanner session create in a java spring boot project using spanner emulator

I am trying to run a basic spring boot application with JPA by using spanner emulator. However, I am getting the below error after startup after hitting any exposed end point.
PERMISSION_DENIED: com.google.api.gax.rpc.PermissionDeniedException: io.grpc.StatusRuntimeException: PERMISSION_DENIED: Caller is missing IAM permission spanner.sessions.create on resource projects/test-project/instances/test-instance/databases/test-database.
Project has been cloned from https://github.com/GoogleCloudPlatform/google-cloud-spanner-hibernate/tree/master/google-cloud-spanner-hibernate-samples/spring-data-jpa-sample
and the only change I have done is updated the application.properties file.
as per my understanding spanner emulator should not have any IAM related issues as it doesn't need any. I am not sure what is causing this issue here. I have verified that the emulator config is the active config and hence I would expect the code to connect to emulator.

The error is a clear indication that your application is not trying to connect to the emulator, but to a real Spanner database. In order to connect to the emulator instead of 'real' Cloud Spanner, you should do one of the following:
Set the environment variable SPANNER_EMULATOR_HOST=localhost:9010
OR: Edit the JDBC connection URL to include the autoConfigEmulator=true property. Your JDBC URL would then become jdbc:cloudspanner:/projects/test-project/instances/test-instance/databases/test-database;autoConfigEmulator=true
The advantage of the second alternative is that the autoConfigEmulator property will not only ensure that the JDBC driver is connecting to the emulator, it will also automatically create the test-instance and test-database on the emulator if they do not already exist.

Localhost:8080, showing 404 Error in Spring Boot Application

I am having some issues in regards to my spring boot microservice, I have been able to successfully connect my microservice to my SQL instance running on Google Cloud, but for some reason when I try to test if the controllers are working using a sample endpoint which simply returns a String "Working" I get a 404 not found error, I have also tried a sample blank project, with no dependency except the ones needed to get Spring Boot up and running, however I still face the same problem, that is I get a 404 Not Found error, even though it is properly compiling and running. I have checked my firewall and it has not blocked the service.
Here is the Controller
VideoController.java
package com.example.demo.Controllers;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class VideoController {
#RequestMapping(path = "/test")
public String index() {
return "Greetings from Spring Boot!";
}
}

#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
DemoApplication is in the com.example.demo.Run package. This means that its component scanning, enabled via #SpringBootApplication, will find components in com.example.demo.Run and in any sub-packages such as com.example.demo.Run.example. The rest of your code, therefore, isn’t in a package where it’ll be found.
I would fix this by moving DemoApplication up into the com.example.demo package. This will mean that components in any of your existing com.example.demo.* packages is found.
Alternatively, you could leave DemoApplication where it is and use the scanBasePackages attribute on #SpringBootApplication to list all your other com.example.demo.* packages. This will be more verbose than moving DemoApplication and would require changes every time you introduce a new package.
As you said your first problem was because of the package level of your main class and Controller class. But the second problem does not seem to depend on refactoring the main class. It's related to conflict of the version of your JDK or another library

It seems that your database username and password are not set with correct property names, as in spring-boot the name of the properties are predefined and only those should be used while giving configuration information. Just try below property keys for username and password :
spring.datasource.username =
spring.datasource.password =
Provide appropriate values..
java.sql.SQLException: Access denied for user ''#'localhost' (using password: NO)
It seems your user password is incorrect. Try to login MySQL with same credentials and it will display the same error.

Derby embedded database not persisting

I am trying to use embedded database derby with spring framework. I can insert the data and read it. Everything works completely fine except for one thing that the database is not persisting. When I close the application and run it again the data is not present. I am guessing that the database is created again but don't know why.
My code:
#Configuration
#ComponentScan
#EnableAutoConfiguration
public class MainClass
{
#Bean
public DataSource dataSource()
{
// no need shutdown, EmbeddedDatabaseFactoryBean will take care of this
EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
EmbeddedDatabase db = builder
.setType(EmbeddedDatabaseType.DERBY) //.HSQL, .H2 or .DERBY
.setName("some-db")
.addScript("/create-db.sql")

create-db.sql contents are
CREATE TABLE table_connection
(
id BIGINT PRIMARY KEY GENERATED ALWAYS AS IDENTITY (START WITH 1, INCREMENT BY 1),
ip VARCHAR(50) UNIQUE,
sessionId VARCHAR(50) DEFAULT NULL
);
SOLUTION:
Accepted answer pointed in right direction but the error was some-db;create=true failed to start. Then I looked at how Netbeans IDE was creating the derby connection. Problem was create=true, I think it's not supposed to be sent with the url but with properties as show in code below:
#Bean
public DataSource dataSource()
{
DriverManagerDataSource dm = new DriverManagerDataSource("jdbc:derby:some-db", "root", "root");
Properties properties = new Properties();
properties.setProperty("create", "true");
dm.setConnectionProperties(properties);
dm.setSchema("APP");
dm.setDriverClassName("org.apache.derby.jdbc.EmbeddedDriver");
return dm;
}
#Bean(name="Application.dataSourceInitializer")
public DataSourceInitializer dataSourceInitializer(DataSource dataSource)
{
final DataSourceInitializer initializer = new DataSourceInitializer();
initializer.setDataSource(dataSource);
try
{
JdbcTemplate jdbc = new JdbcTemplate(dataSource);
jdbc.queryForList("SELECT id FROM table_connection");
}
catch(Exception e)
{
initializer.setDatabasePopulator(databasePopulator());
}
return initializer;
}
#Value("classpath:create-db.sql")
private Resource schemaScript;
private DatabasePopulator databasePopulator()
{
final ResourceDatabasePopulator populator = new ResourceDatabasePopulator();
populator.addScript(schemaScript);
return populator;
}
Script create-db.sql can give error if table already exists as no IF EXISTS in derby so wrapped it in try-catch.
Bean datasourceInitializer is named explicitly 'Application.dataSourceInitializer' as spring auto-configuration tends to override it. Check it here.
This is the core of your problem: jdbc:derby:memory:some-db;create=true
When you say 'memory' in your Derby JDBC Connection URL, you are telling Derby explicitly to make a non-durable database.
If you remove the 'memory:' from your JDBC Connectino URL, Derby will create a persistent, durable database in the 'some-db' directory on your hard disk.
